\chapter{Theoretical Study of technologies}

previous chapter pointed out what is the problem. here, stess is given on what:
- are the characteristics of applicable things
- what additional consraints are posed by the different things

two main points of the chapter being to address:
- dynamic edge placement
- capacity provisioning in case of multiple edges

\section{Dynamic link allocation}

- typical graph theory problem
- solved by routing protocols
- why OSPF and not IS-IS or RIP?


\section{Capacity provisioning}

\subsection{Layer 2 link aggregation}

\subsection{Multihoming Transport Layer protocols}

\subsection{OSPF load balancing}
